Vibrant 10954 Bellmouth Velocity Stack 5" Inlet x 8.75" Bellmouth

The Vibrant Performance Bellmouth Velocity Stack is designed to maximize airflow into intake systems by providing a smooth, gradual transition that reduces turbulence and increases velocity. This precision-engineered aluminum velocity stack features a 5-inch inlet outer diameter and an 8.75-inch bellmouth outer diameter, making it ideal for high-performance engine builds, custom intake manifolds, and racing applications.

Key Features:

• CNC-machined aluminum construction for durability and lightweight performance
• 5-inch inlet outer diameter for secure fitment
• 8.75-inch bellmouth outer diameter provides optimal air entry profile
• Smooth, radiused bellmouth design minimizes airflow restriction and turbulence
• Ideal for individual throttle body setups, turbocharger inlets, and custom intake systems
• Polished finish for professional appearance

Bellmouth velocity stacks are essential components in high-performance applications where maximizing airflow efficiency is critical. The gradual flare of the bellmouth allows air to enter the intake system with minimal resistance, improving volumetric efficiency and throttle response. Perfect for drag racing, road racing, and custom engine builds where every CFM counts.
